` Application filed April s,

To all ivhom t may concern:

Be itknown that I, JOHN a citizen Aof the United States, residin atOmaha, in the county of Douglas and tate of Nebraska, have inventedcertain new and useful Improvements in Non-Skid Devices, of which thefollowing isa specification.

This invention relates to improvements in B. NESMEYER,

anti-skid devices especially adapted for'use on vehicle wheels.

An important' object of this invention is to provide a non-skidattachment for vehicle wheels which may be readily and convenientlyapplied to a vehicle wheelfor increasing the traction of the same as theoccasion requires.

A further object of this invention is to provide a non-skid attachmentfor vehicle .wheels which comprises a plurality of rows of oblong treadblocks detachably strung on or carried byl a flexible element in theform of a cable and capable of being' replaced when worn as the resultof continued use.

The invention furtherv aims to provide a non-skid attachment having aplurality of spaced tread elements adapted to be eX- tended diagonallyacross the tread of a vehicle tire so that as the tire rotates each ofthe several tread elements will be gradually engaged with the groundwhereby the objectionable shocks transmitted to the power plant of thevehicle as the result of sudden engagement with the tread elements withthe ground are eliminated. f

A further object of this invention is to provide a non-skid attachmentfor vehicle wheels which is simple, eiicient in use and cheap tomanufacture.

Otler objects and advantages of the invention will be apparent durlngthe course of the following description.

In the accompanying drawings formin a part of this application and inwhich l1ke numerals are employed to designate like parts throughout thesame, l

of illustration is shown a' preferredjembodiment of the lnvention, thenumeral 10 gen- `erally designates a vehicle wheel having aplurality lofradial spokes 11 which have a felly 12 connected thereto. lA-rirn 15 ofany des1red type may be arranged about the felly 12 for detachablysecuring the tire 16 about the wheel. The improved non-skid chainforming the subject matter of this ap-4 plication embodies an attachingring 18 arranged at one side of the spokes and secured to the same bypairs of bolts 19. With particular reference to 'Fig. 5, it will benoted that the bolts of each pair are ,arranged on opposite sides of theadjacent spoke and eX- tend through elongated plates 20 arranged onopposite sides of the spoke and drawn tightly into engagement with thesame by fastening nuts 21. The bolts 19 are spaced from contact with thespokes by tubular cushioning, elements 22 carried by the bolts betweenthe ring 18 and the plates 20. The spokes are therefore prevented 'frombeinlg scratched orl marred through contact wit the bolts 19.

The ring 18 serves as a connecting medium for a plurality of tractiondevices generally designated by the numeral21.` As partlcularlyillustrated in Figs. 1 and 4, the traction devices extend in spacedrelation diagonally of the tire so that as the wheel rotates thetraction devices will be gradually engaged" with the ground. That 1s tosay, the several traction devices arranged about the tire are notsquarely presented to the ground but are gradually brought into contactwith the ground so-that-continuous and unbroken traction will be hadbetween the ground and the wheels. In this manner no objectionableshocks are. transmitted from the traction wheels to the power plant ofthe In the drawingswherein for the purpose I the view illustrating fthevehicle as the result of sudden engagement e of the traction deviceswith the ground Each traction device 24' comprises a cable 25 composedof a plurality of twisted strands of wire. As illustrated particularlyin Fig.

I' mediate its-ends so as to form a pair of cable.V

`.sections upon which are strun of elongated blocks 26 adapte 1 5 f 18and is heldin position'by afnut 31. t

1, the cable 2 5 isA foldedupon itself interfor engagef ment with theground. The elongated blocks 26 may be formed of any suitable wear--resisting material and are rovided with openings near their ends whichreceive the sections of the cable. The intermediate por, tion ofthecable in being bent upon itself| defines a loop 28 connected tov-theapertured head of an e bolt 29. As particularly traction device`24 isextended through the transverse opening 30 in the attaching .rin

will `be noted that the nut 3l may be adjusted on the shank of the eyebolt 29 for adjustably securing the traction device about the tire. Theend portions of the cables 25 are extended through transverse openings32 in the attaching ring 18 and are l. engaged by cable clamps 33. Eachcable clamp 33 comprises a grooved body 34 having a U-bolt 35 connectedthereto and -arranged 4on opposite'sides of the end portions of thecable. Upon being tightened by nuts includes. a pairof sections/37detachablyv able fastening means.

36 the U-bolt 35 is drawn into locking engagement with the adjacentportions of the cabl so' that thesa'me' is securely held in v position.

The end blocks of each row .of tread bloclis connected 'by a screw bolt38 or other suit- By this construction, the end vblocks may belocked ina desired position on the cable for securing the When 'it is innerblocksin a set position. desired toI remove any of the inner blocks, oneof the end blocks may be detached for allowing the end blocks to be slid011:' the free ends of the cable. vThe cable clamp must, however, bedetached prior to removing any of the blocksv from the sections of thecable. By this construction any'of the blocks may be replaced uponbecoming The sections of the cable 25 are prevented from scratchmg orotherwise marring the 'felly and'spokes of .the -wheel by rubber tubes40 which may be applied to the cable.

In applying the improved non-skid device, the attaching ring 18 is, ofcourse, secured to one'side of the wheel by the bolts 19 and theassociated plates 20.` With the attaching plate 18 thus secured to oneside of the` wheel adjacent the felly of the Same, the eye bolts a.plurality 29 of ythe traction devices may be kconnected with the ringafter which' the cable sections may be moved.about'theo-uter Side 'ofjthe tire for positioning..the/":treadf blocks 26 about the tire.connecting-the free ends of the cable to the ring, the tread blocks kareof course extended' diagonally vof the tire so that as the wheel rotatesthe several tread devices will be gradually engaged with the ground.When it is desired to detach any of the blocks, it is merely necessaryto remove the proper cable clamp 33 and the end block 37 to lallow theblocks 26 to be vmoved off the cable sections.

' With reference to the foregoing descrip- .tion taken in connectionwith the accompanying drawings, it will be observed that the treadblocks do not injure the tire since lthey are flatly engaged with thetread of the tire. In'practice as many of the traction devices asnecessary may be employed. f i

It i s to be understood that the form of the invention herewith shownand described is to be taken as a preferred embodiment of the sameandthat' such minor changes 1n construction and arrangement of parts may bemade as will remain within the spiritof the invention and the scope ofwhat is claimed.

Having thus described the invention, what is claimed as new is:

1. A nonskid attachment for vvehicle wheels comprising a flexible.element bentintermediate its ends to form .apair of sections and a'.loop, an annular attaching element, a fastening device extend-ing fromsaid loop and engaged with said annular attach- 'ing element, and meansto connect the free ends of said flexible element and to secure the sameto said annular attaching element.

2. A traction device for vehicle wheels` g wheels comprising a cabledoubled upon itself to form a pair of sections and a loop,

tread devices carried by said sections, an at* taching member, a cableclamp connecting the ends of,said cable and securing the same to saidattaching member, and means whereby said l`oop may1.be connected to saidattaching member.
